Abstract: For face 3D reconstruction, a color 3D reconstruction method was put forward based on RGB laser scanning system. First, the mapping relationship between the pix-coordinates and the world- coordinates was determined by using a calibration plate; and a standard color plate was used for calibrating the RGB color data, in which the value acquired by digital camera and the value provided by the standard color plate had fitted. Second, the face 3D reconstruction experiment was introduced in detail including the steps of scanning, calibration and image processing. And the face could be 3D reconstructed with color texture at millimeter scales. Then, the 3D data were matched by ICP method, and could be exported to other software as a 3D model. This method simplifies the algorithm of the calibration and 3D reconstruction, and the system is low cost which can be widely used for 3D reconstruction of many kinds of objects.
